水压设备动态特性与稳定域

Dynamic Characteristics and Stable Region of Water Pressure Equipment

对高压水设备及应用直动式溢流阀的液压系统的动态特性进行了研究.研究路径是:建立了系统的微分方程组,微分方程线性化,利用龙格库塔法进行溢流阀芯的动态仿真.针对系统安装蓄能器与否两种工况进行分析,指出系统振动原因和稳定域划分方法以及影响系统稳定性的因素.

This paper deals with the dynamic characteristics of water pressure equipment and the systems with popped valve.We set up the equations,linearizes them and make simulation with Runge-Kutta method.We ale analyse the situation fixed accumulator or without it.We pointed out the reason of vibration,the method of dividing the stable region,effecting factors of the equipment.
